One thing to note is that for the form you want, you need to explicitly define y as a function of x. The Nelder{Mead method attempts to minimize a scalar-valued nonlinear func-tion of nreal variables using only function values, without any derivative information (explicit or implicit). The internal energy in this way is not much better, because we usually do forget about some parts of it (oscillational modes, rest mass, binding energies, etc).

However I was told that this solution could not be applied to this question because I should be solving for the total derivative. The Truesdell rate is simply the time derivative of the pull back of the Kirchhoff stress with the deformation gradient, pushed forward by the deformation gradient multiplied by J (or J^-1 I forget which) - in other words, it is basically th Lie derivative of the Kirchhoff stress upto a mutiple of j or J^-1. Chapter 3 - Kinematics: Lagrangian vs. Then, equation (12) becomes. simply write down Newton’s second law, F = m~a, as a function of the total derivative (referred to as material derivative in ). Notice that if x is actually a scalar in Convention 3 then the resulting Jacobian matrix is a m 1 matrix; that is, a single column (a vector). Note that the above conservation laws implies that the rate of change of the advective (material) derivative of the momentum equals the gradient of pressure.
